ζ Lupi (Latinised as Zeta Lupi) is the brighter component of a wide double star in the constellation Lupus, consisting of an orange-hued primary and a fainter secondary with a golden-yellow hue.
[2] Based upon an annual parallax shift of 27.80[1] mas as seen from Earth, it is located 117.3 light-years from the Sun.
[3] The primary, component A, is an evolved G-type giant star with a visual magnitude of 3.50[3] and a stellar classification of G7 III.
[4] This is a red clump star, indicating that it is generating energy through the thermonuclear fusion of helium in its core region.
Zeta Lupi is 50 times more luminous than the Sun, emitting this energy from its photosphere at an effective temperature of 5114 K.[7] The secondary, component B, has a visual magnitude of 6.74.
